r4Aivrisriiriune DEVICE.

To. all fw hom `it may concern `Be it known that we, GEORGE KAEOIJ and ANDREW BAn'rUs, .citizens'pf Hungary and the Unitedk States, respectively, residing at Wyatt, in the county of Harrison and State of West Virginia,have invented certain new and useful Improvements in Antislipping cation.

This invention relates toy an anti-slipping device for boots or shoes which is adapted to be applied to the 4heel of the shoe to enable the user to walk safely on icy pavements, walks or other surfaces. l g;

The invention has for an obj ectto provide a simple and inexpensive device vof this kind ywhich may be used in connection with4 any ordinary heel and attached and detached' as desired. f

For further comprehension ofthe invention, and of the objectsand advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features'of the invention are'more par- Figure 1 of the drawingsis a perspective view of an anti-slipping device constructedfaccording to our invention.

Fig. 2 is a fragmentary horizontal section takenon the line2-2 of Fig. 3. i

,.Fig.y 3 is a transverse section through the front portion of the device along the line 3-3 of Fig. 1.`

As here shown our improved device comprises briefly a plate element adapted to fit upon the heel of the shoe and divided longitudinally intok a pair of sections 1 and 2, the two sections jointly corresponding in outline to the heel of the shoe. These sections have upstanding flanges,'3 and 4 respectively, leX- tending around the side and curved rear edge thereof, these flanges being Vhinged together at the rear of the plate elementv as at 5 ,whereby the two sections may be opened or closed toward one another, the flangesk 3 and 4 con stituting in eii'ect a pair of jaws which grip the heel.

In order to enable the device to be iitted on heels of ydifferent sizes the adjacent edges of' y specificati@ f Letzersratent. Patented May '24,1921 Application filed August 24, 1920. seriaijiro. 405,612.

In connection with our improved ydevicerv we employ a novel clampingmeans forsecuring it upon a heel. This means comprises a tie bar 8 which extends between the yflanges 3 and 4fat the front yend of the device yand is capable of bodily adjustment transverselyto i itself .for application to heels of different sizes. To this end the flanges 3 .and 4 are formed with slots 9 and 10 extendingy rearwardly a distance from the kfront ends there,

of. Formed in thelange 3 areafseries of longitudinally spaced'verti'caly borings 11 which intersect the slot 9. Projecting into these'borings are the prongs 12 ofa fork element .13, which prongs are adapted toserve as hinge pintles for oneend of the bar`8.`

Each of these prongsis formed'with a cir- 1 cumferential recess such as 14 `which ,registerswith the slot 9 when the fork is in place,

while thefend of the bar 8 hasV anl opening.

`formed with a parti-spherical projection 18 adaptedv toengage in the ,desiredV one of a series of complementary recesses 19 Aon the Outer face of the flange 4, these recesses 19 `15Ntherein of. slightly larger diameter. .than

the prongs 12, through which opening being positioned along the flange 4 in corre- 1 spondence with the borings 11 in the flange 3. The projection 18 is pressed into engagement with the recesses 19 by a coiled expansion spring 20 surrounding the pin 16 in the cup 17 and bearing between the closed end of said, cup andthe enlarged head 21 of the to keep the wall of thezperforation 15 in the opposite end of the barfin engagement with the recess 14 intheprong ofthe fork '13,k

holding the latter againstdisplacement.

It is believed that the manner ofuse of our improved anti-slipping device will heapparent from the above description, it being obvious that the spring 20, acting through pin.. As will be obvious, the spring 20 is pulling also on the bar 8 and its pressure acts l bar 8, will hold kthe flanges 3, 4 in gripping n.

engagement with the sides of the heel. The

bar 8 may be adjusted to accommodate diferent sized heels by partially pulling out the fork 13 and bringing the aperture 15 in the cess 14 in the prong 12 by swinging thepi'n t 17 out of the end of the slot 10 or pressing inwardly on the head of the pin 16.

Having thus described our invention what we claim as new and desire to protect by Letters Patent of theUnited States is as follows: t l t 1. An anti-slipping device comprising a pair of plate sections hinged together at one end and provided with spikes, means on said plate sections adapted to grip the sidesof a heel, a bar hinged at one end to the free end of one section, a member on the other end of the bar adapted to engage the other section to cause the device to 4grip a heel, and a spring pressing said member against the said other section. i

` 2. `An anti-slipping device comprising `a pair of hinged plate sections each having an upstanding flange extending along the side and rear Vedge thereof, the flange on one section being slotted rearwardly for a distance from the" front end thereof, a bar hinged at one end to the front end of the other flange and adapted to be swung into and out of engagement with thesaid slot, a head slidable on thel said bar, and a spring on said bar adapted to press said head against the said slotted flange. y

3. An anti-slipping device comprising a pair of plate sections each having an upstand flange extending alon-g the side and rear edge thereof said flanges having slots extending rearwardly therein from the front ends thereof, means hinging said sections together at their rear ends, a locking barextending between the said flanges and engaging in the said slots, and means providing for bodily adjustment of said bar transversely of itself to different locking positions. j

4. An anti-slipping device comprising a pair of plate sections each having an upstanding flange extending along the side and rear edge thereof said flanges having. slots extending rearwardly therein from the front ends thereof, means hinging said sections t0- gether at their rear ends, a `locking bar extending between the said flanges and engaging in the said slots, and means providing for bodily adjustment of said bar transversely of itselfto different locking positions, said means including a fork element carried inone of said flanges and having a Vplurality of prongs adapted to `serve as desired as hinge pintles for any end of the said bar.

5. An anti-slipping `device comprising a pair of plate sections-,each having an upstanding flange extending along the side and rear edge thereof, saidiflanges having slots extending rearwardly therein from the front ends thereof, means'hinging said sections together at theirrear ends, a locking bar extending betweenlthe said flanges and engaging in the said slots, a fork element carried in onevof said flanges and having a plurality of prongs adapted to serve as desired as l hin e pintles for one end of the said bar, sait? prongs having recesses 'in j the sides thereof adapted tto be engaged by the bar to hold the fork against displacement, `and a device including a spring upon the opposite end of the bar adapted to yieldingly hold the said end in engagement lwith theadjacent flange and the bar in engagement with the recess in the prong. y
